Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed. October 30, 1919. Serial No. 334,408.

1/ aZl to com it may concern Be it known that I, TENZEL LEINERT, a citizen of Russia, and a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Bearings, of which the following is a specification,

This invention relates to an improved bearing for supporting receptacles or other elements that are adapted to be partially rotating, as in tilting bodies, and is adapted to relieve the support and the supported elenient of shocks incidental to the stopping of the tilting or partial rotation.

in order to fully and clearly illustrate one construction in which this device is used, I will describe and illustrate its use in connection with a tiltingtank, such as is fully set lorth in my Patent No. 1,319,478, issued Oct. 2 1, 1919, it having been previously thecustom to mount the tanks on the supports by means of knife edges. In tilting from a horizontal to an angular position, especially in large tanks where heavy Weights have to be handled, the center of gravity moves from a position'vortically relative to the supporting point to one inclined thereto, and the angular resistance is tangential to the are described by the center of gravity.

The components oil such tangential force and resistance are vertical and horizontal, the vertical one being taken care of by a suitable bumper or spring, but the horizontal one has heretofore not been compensated for, which results in a tendency to horizontal movement at the pivot, which is unsatisfactory and which subjects the construction to considerable strain. To overcome this I have devised the present bearing, which permits a limited horizontal movement which is yieldingly resisted and which so cushions the stopping of the tilting movement that there isno excessive strain put on any part of the structure.

It will be understood that the device can be used in other forms of receptacles and supports, and it will come within the scope of thisinvention to apply this deviceto such situations or devices as will permit of its use.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a side view of a tilting tank provided with my improved bearing. Fig. 2 is an enlarged face view of the bearing, the left half portion thereof being shown in section. Fig. 3 is a vertical section taken through the con tor of l ig. 2, and Fig. .4; is a view similar to Fig. 8, showing a modified form of structure. In the drawing, is a tank representing the supported element, and the tank is adapted to tilt 011 the support 11, and the tilting, both forward and backward, from. and to a horizontal position is of a nature to cause shock to the support and the tank, especially at the bearing. i

In the case of large tanks the contents, suchas water, makes the tank very heavy and the bearing is subject to considerable displacement when the tilting is stopped. In measuring tanks the journal. or bearing must be freely rotatable in order to insure accuracy, such as when the tilting tank is a meter. The center of gravity of the tank will be assured at a when the tank is horizontal, and as at b when the tank completes its forward movement; then the force .0 tangential to the are d described by the path of the center of gravity. An angular resistance perpendicular to the force 0 is impractical, as with different Weights or materials to be used in the tank, the location oi the center of gravity varies. It thus becomes necessary to take care of the vertical component e and the horizontal component f.

The bumper l2 and the bolt 13, actuated by the spring i i, are illustrations of means employed to compensate for and cushion the vertical component c. To cushion the horizontal component 7' is the function of the present invention, and it consists of a journal or bearing 15, which is constructed so to yieldingly resist horizontal movement, but is fixed against vertical movement, especially downward.

One form of bearing is illustrated in Figs. .3 and 3. The frame 16 is secured to the top of the support 11 and a casing 17 of the bearing rests on the floor of the frame, usually 011 a smooth insert 18, which permits the casing 17 to roll thereon. The casing in closes any desired form of anti-friction bearing, such as a ball bearing 19,which receives the shaft 20 oi. the tank 10.

To yieldingly resist the rolling motion of the journal 17, in other words, to cushion the horizontal movement, I prefer to arrange springs which act to perform this function. One form comprises a bolt 91 which is slidablein the frame 16, and a spring 22 embraces the bolt and abuts at one end on the frame and at the other end on a nut 23, which is screwed on the bolt 21 and thus acts to adjust the tension of the spring 22. A sleeve 24 can be placed over the bolt and thus limits the movement of the vieldthe; spring 28 and having a shoulder 29 V which engages with the side of the frame 16 to limit the movement of the bolt 25. To prevent lateral movement of the casing I prefer to provide the floor plate 18 with a flange 30 which insures the journal 17 roll ing straight.

In Fig. 4 1 illustrate a modified form in which the front 31 of the frame is provided with a bolt 82 which is screw-threaded into the frame, and the end of the bolt engages the end of the shaft 20 and is preferably locked in position by a lock nut 33. This is a modified construction for preventing lateral movement of the shaft 20, and consequently of thejournal 17, as will be evident.

The bolt 21 is usually arranged so that it normally is just out of contact with the journal, this permitting a free operation of the (lGViLG in that the journal has a very short initial start of its rolling motion, which is advantageous in finely balanced devices, such as meters, on which the bearing is used.

I claim:

1. A bearing comprising a rotatable shaft,

a journal for the shaft, a support on which the journal can roll, a bolt to engage the journal, and a spring for resisting movement of the bolt.

2. A bearing comprising a. rotatable shaft, a journal for the shaft, a support on which the journal can roll, a bolt to engage the journal, :1 spring for resisting movement of the bolt, and means for adjusting the tension of the spring.

3. A bearing comprising a fixed support, an insert on said support, the insert having a smooth top surface, a shaft, a journal in \VlllLll the shaft is mounted, the journal rolling freely on the insert, means for prcventing outward endwise movement of the journal, and a spring disposed so as to be engaged by the journal after it moves and normally out of operative contact therewith.

In testimony that I claim the foregoing, 1 have hereto set my hand, this 28th day of October, 1919 VVENZEL LEINERT.
